Horn on permantley

[paulwilson]

the horn sounds permantley, i understand that the live feed in there always but even if i remove the horn push assembley and leave the single cable poking through without the end nipple touching earth, the horn will sound, i have now disconnected it, any ideas please

Must be a short in the wiring to the button - pull the purple/black wire off the horn - does it still sound ?

Roy is spot on as always, so you are looking for a chaffed/ pinched /damaged piece of wiring.Around the steering colum / under the dash area is the usual culprit.Have you done any work there recently ,which might have disturbed it ? If just the insulation is damaged, you can repair with a bit of electrical tape.

it could be something to do with slipring on the column a little bird told me, once i have removed the steering wheel what am i looking for

I'm no expert but If you disconnect the purple wire behind the dashboard (flaw in this plan is there might be another purple wire for the interior light) wouldn't that find out where the earth is happening?

- If the horn stops the problem is with the steering wheel connections/horn push

- if it doesn't stop its between the dashboard and the horn

If the short was on the purple wire it would blow the fuse and the horn would NOT sound..... The purple/black wire is the culprit.....

Yes sorry, the purple and black wire!

[paulwilson]

none of the above has worked, i have to look at the steering wheel removal, sliprings maybe, what do i have to do, any ideas?

It must have worked - with the purple/black wire off the horn - it can't possibly blow! Is this the case? To remove wheel etc - first disconnect the battery. Remove horn push - loosen the nut - then tug the wheel (or bang it from below) to free it on the splines - then remove the nut and pull the wheel off.
